HTML Minifier

An HTML minifier removes unnecessary characters from your HTML document (such as spaces, line breaks, and comments) without changing how the webpage looks or functions. This results in a much smaller file.

Minification removes actual characters from the source code. Gzip or Brotli are server-level compression algorithms that compress the file before sending it over the network. For maximum performance, you should use both together.

No, your inline <style> and <script> blocks remain intact. However, if you check the specific options in our tool, we can safely minify the contents inside those tags as well.
